Forage Under Sprayed Trees

Categories: Fruit Growing

Is it safe to use arsenical sprays in a pear orchard in which alfalfa is

raised between the trees and afterward cut and fed to cattle?

It was fully demonstrated by experiment about 25 years ago that herbage

under trees sprayed with paris green at the rate of 1 pound to 160

gallons of water was not injurious to animals pasturing upon it. We are

not aware that such an experiment has been made with the more recently

used arsenates - which can be used with a much higher amount of arsenic

to the gallon because they do not injure the foliage - to determine

whether the herbage below would be poisonous or not. Presumably not,

because modern spraying does not admit as much loss from run-off as was

the case with old Spraying methods.
